The moment you have your date and location decided on, it is time to send out your save-the-date cards. It is fine if you have not closed up on the exact location, just letting them know the state and city your wedding will be held is sufficient.
On the other hand, if you are not sure whether a particular person or couple will be invited to the wedding, don’t send them a save-the-date card. And there is really no reason, and it’s a waste of your precious money, to buy and send these notices when all of your guests live relatively nearby or the wedding will not occur during a busy time of the year.
Rules & Etiquette – Again, few rules apply. The only information you must include is your names and wedding date, although I suggest including location information as well so wedding guests can begin their travel plans. Aim to send save-the-date cards soon after you secure your date and venue, or about 4-6 months prior to your wedding. Remember, everyone who receives a save-the-date also receives an invitation, so have your guest list finalized prior to sending them. You can, however, always add guests later (there is no rule that says everyone must receive a save-the-date card). Although formal replies are not required, you can get preliminary attendance estimates through word-of-mouth.
Save the date cards are simple cards that give limited information. You can announce your engagement and announce the date of your wedding. It doesn’t have to list the location unless it’s going to be out of town for part or all of your guests. There are a couple of options you have when you use save the date cards. You can have postcards printed and spend less on postage or you can create a card to insert in an envelope.
You want your save-the-date to look unique, personalized and funky; so that it can attract your guests’ attention and make them want to attend your wedding. Save-the-date cards for weddings should ideally reflect the couple’s personality, and the wedding tone.
